Moved mcgrab(1) into a separate directory -- our .mk infrastructure

doesn't currently have support for building multiple programs in a
single makefile.

While here, fixed manpages and makefiles (missing dependencies).

+multicasts in hardware and has to switch to promiscuous or
+multicast promiscuous mode.
+A successful test does not have any
+result, but an unsuccessful test will have deleterious side effects.
